On Tue, Mar 08, 2016 at 11:22:19PM -0500, Alexander Walters complained about py.exe:
It modifies the windows registry to set a file association, which is a pain when you want double clicking a python file to open a text editor. So you have to change file associations, which was made really painful in recent versions of windows.
Sounds like your real beef is with Windows, not py.exe.
As a programmer, couldn't you script something to change the file association and make it easier? When the pain of doing something gets greater than the pain of writing a short script, that's what I do.
If you're having this problem, perhaps others are too, and the installer could make the file association change optional?
